In the accompanying drawings 1 have shown an atomizer or spraying device em bcciying; one form of .my invention and which will serve at the some time a means by which to describe my improved method.

used the nozzle may be secured "directly to pipe 1.22 'Asshcwn in"Fi-gs.4 and '5, the

nozzle is provielecl with substsntislly loil tuclinsl passages 4 which deliver the bi an annular channel on thejfsee ofthe nozzle. Resting on this face is a removable .c'leniher 6 in the form of o Wssher',.th e cen trsl opening of which is of less diaineter than the diameter of the channel 5. Extending tangentially to the wall of the opening.

This chamber is preferably dome shaped so that its upper portion 11 is of less diameter than its lower portion, and

in the Willi of its upper portion an opening;

is provided through which the spray is discharged, such opening being at a point other than one coin'centric with the axis of revolution. of the liquid. In the form shown this opening is a slot 1:2 iocatedin a plane at suhstantisllys right-angle to the axis of the tip, such slot limiting the direction of the spray issuing from the tip and preventingits taking :1 form concentric about'the axis of" revolutioii of the liquid.

In Fig. 6 l have shown a sli ht modification of the tip in which the chamber 10 has a wider base then in the form shown in Figs. 4: one 5,. ami the side walls converging upwaroliy'to the upper portion. 2

spraying medium, and flowing through the passages 4:, annular channel 5, and the tangentml passages 8 is delivered with a rapid whirling motion into the chamber it). The" particles er oil upon reaching the slot 12 1y ofi tangentially, clue to the action of centrifuggil force, the whirlingof the "liquid being so rapid as to cause some portions to fiy in one direction and some in another, as "indicated in l, but silfiy in substantially the plane: A fist even spray is, therefore, produced which, on being ignited, results in a flat flame as in atomizers using spraying media.

I am aware that spraying devices or oil issues from the tip in a conical form resulting, with oil fuel, in what is known as a round flame.

I am also aware that spraying devices have been used in which anatomlzmg or spraying medium, such as compressed air or steam,

is employed-to spray the liquid, and that such'devices haveproduced'a spray issuing from the tip in a single plane resulting in a fiat or fan-tail form o'fspray, or what is known in the case of liquid fuel as a flat flame.

There are many instances where the fiat flame is best adapted to the local conditions existing in a furnace, giving a more uniform distribution of heat and better eiiiciency. There are, in fact, conditions in which a round flame burner cannot be used to give the desired results, and the superiorityof the flat flame burner has resulted in the entire abandonment of the round flame burners in certain localities and in certain forms of furnaces. On the other hand, there are many instances in which oil is used as a fuel wherein the local conditions practically prohibit the use of atomizers in which an atomiaing medium such as compressed air or steam is employed. his is true particularly in connection with marine work where steam cannot be used on account of the loss of fresh water and where compressed air necessitates the installation of heavy and objcctionable compressing machinery 'and the use of large and unwieldy pipes throughout the boiler room. In installations of this character the class of oil burners in which oil is sprayed or atomized by means of a whirling motion imparted to the oil by means of pressure has practically supplanted all other types, and it is to a device of this character that the present invention is directed. In the prcsent device however the liquid is atomized or sprayed without the use of compressed air or steam, thereby obtaining the advantages of the flat flame without the objectionable "features incident to the employment ofcompressed air or steam, and I desire, therefore, to claim broadly. the atomization of a liquid unmixed with air or steam, by permitting it to escape under pressure in substantially a single plane. Vvhile I have described the passages S as tangential to the wall of the washer 6 and the wall of the chamber 10, I desire to include within said term any degree of cocentricity of said passages which will give to the liquid a rapid whirling motion.

What I claim and desire to secure by Let,

ters Patent of the United States is 1. The method of producing a flat-tam shaped spray of oil for firing, without using steam or air for atomizing the oil, which consists in forcing a continuous stream of oil from an oil supply under pressure into a chamber in a tangential direction to give the oil a whirling motion, and then permitting the oil to escape in an atomized form or spray in substantially a single plane; substantially as described.

2. The method of producing a fiat fanshaped spray of oil for firing without using steam or air for atomizing the oil, which consists in forcing a continuous stream of oil from an oil supply under pressure into a chamber in a tangential direction to give the oil a whirling motion, and then permitting the oil to escape in an atomized form or spray in a general radial direction in substantially a single plane; substantially as described. a
